A steam generator 36, for regenerating the absorbent, leads into the containers through valves 37 and 38 which are controlled by the programme control mechanism 22. The fan 11 is operated constantly and if the flaps 27, 28 of the machine are closed excess pressure builds up in conduit 13 producing a signal causing valve 35 to open. Air is thus recycled to the inlet through the by-pass 34. Independently of the machines 25, periodical changeover of the containers is effected by control 22. Shortly before changeover, steam is allowed through to the container which is to come on flow. On changeover, the control also opens valves 44, 45, so that the condenser 12 is supplied with coolant and the pre-heater 14 with heat, e.g. steam.

Title: Method and devices for constructing foundation piles in the ground
IPC: E02D5/38
Filed: 1951-09-05
Abstract: 690,141. Piles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. Sept. 5, 1951 [Sept. 15, 1950], No. 21012/51. Class 68(ii) The making of piles by driving a tube a into the ground by ramming a plug b in the bottom of the tube, the plug engaging the inner wall of the tube frictionally, is characterized in that the (fresh and almost dry) concrete for forming the plug is contained in a deformable wrapper c (e.g. a paper bag). This has the advantage that the concrete can be introduced into the tube from the bottom instead of pouring it from the top. The bag may be held initially by straps or the like 4 secured to the tube; the straps may be fractured during the ramming so that the plug may spread somewhat outside the bottom of the tube. After sinking, the tube is filled with concrete, which may be reinforced, and the tube is left in the ground. The bottom of the tube may be thickened as shown at 1 in either Figure.

Title: A process for improving yarns and fabrics having fibres of natural or regenerated cellulose
IPC: D06M11/55
Filed: 1939-07-20
Abstract: 533,848. Treating textiles. HEBERLEIN & CO., AKT.-GES. July 20, 1939, No. 21089. Convention date, Aug. 23, 1938. [Class 15 (ii)] Natural or regenerated cellulose fabrics and yarns are improved by treatment with swelling agents having a parchmentizing or shrinking action in which before, during or after such treatment insoluble precipitates are produced in the fibre by chemical reaction between solutions of soluble substances. Suitable precipitates may be produced by impregnation with a solution containing a polyvalent metal cation, e.g. calcium or barium, followed by a solution containing an acid anion, e.g. a sulphate or sulphuric acid. Barium thiocyanate, if desired so dilute as to exert no swelling action, or barium acetate may be used in the first impregnant. Swelling agents, e.g. concentrated formic acid solution may be added to the first bath. Strong solutions of Glauber salts may be used for the second bath. Alternatively, solutions containing metal cations may be used, e.g. aluminium sulphate. The procedure may be reversed, e.g. treatment with sodium tungstate may be followed by barium chloride. Patterned effects may be obtained by printing with thickened solutions containing gum tragacanth. Swelling agents having a parchmentizing or stiffening action are sulphuric acid, concentrated zinc chloride solution, concentrated calcium thiocyanate solution or caustic soda solution of mercerizing strength used below 0‹C.; those having a shrinking action are caustic soda of mercerizing strength used at ordinary temperature or reagents of the first category in concentrations below parchmentizing strength. Examples describe the production of linen and woollen effects on cretonne and muslin. The process may be combined with a cellulose ether dressing.

Gas meters.-In a gas meter with a bellows, membrane, or the like dividing a casing into two measuring-chambers which are placed alternately in communication with the inlet and outlet by means of valves operated by the bellows &c., the chambers are arranged in the casing so that one wall of the casing forms the bottom of both chambers and the inlet and outlet valves of the chambers are arranged directly in that wall. As shown, the bellows 1 divide the casing 2 into inner and outer chambers A, B, the central part of the wall 2<a> forming the bottom of the chamber A and the outer portion of the wall forming the annular bottom of the chamber B. The inlet valves 3, 5 of the chambers are located on the outer side of the wall 2<a> and secured to a pivoted lever 7, while the outlet valves 4, 6 are located on the inner side and secured to a pivoted lever 8. The valves are arranged so that the inlet valve 3 and outlet valve 6 are opened simultaneously when the valves 4, 5 are closed, and vice versa. The spindles of the valves 3, 4 are connected to the armature 9 of a horseshoe magnet 10, and an arm 11 keeps the armature between the shanks of the magnet. Two springs 12, 12' secured on opposite sides of the arm 11 are operated by an arm 14 secured to the movable bottom 13 of the bellows. When the valves 3, 6 are open, gas passes from the inlet 16 into the chamber A, and the spring 12 moves the arm 11 so that the armature 9 is attracted to the opposite shank of the magnet 10, thereby closing the valves 3, 5 and opening the valves 4, 6. The gas then flows into the chamber B and the gas from the chamber A is forced out through the outlet 17, the arm 9 being returned by the spring 12' and reversing the position of the valves. The bellows is connected to a counter 15.
